Glass Bottle Interior Spray Coating Solution
Automatic inner spray machine & turnkey coating line for perfume, cosmetic, pharma, wine & food glass bottles. Narrow neck down to 5mm, zero exterior contamination, PLC recipe control, UV / water-based / solvent compatible.
Solution Overview
Geetech: Precision Interior Spray Coating for Glass Bottles
Designed for narrow-neck glass containers, Geetech interior spray machines use extended-nozzle guns and multi-axis positioning to coat the inner wall with lacquer, paint, or UV material. From standalone units to fully automated turnkey lines, we deliver high-flexibility, low-waste internal coating solutions for perfume, cosmetic, pharmaceutical, wine, and food-grade glass bottles.
Narrow Neck Expert
Handles bottle neck diameters down to 5mm. Extended nozzle reaches deep into the bottle, ensuring full coverage at shoulder and bottom with zero dead zones.
Zero Exterior Contamination
Negative-pressure recovery combined with external masking fixtures ensures the bottle exterior stays completely clean during interior spraying.
Multi-Coating Compatible
Supports solvent-based, water-based, and UV-cure coatings. One platform handles primer, basecoat, and clearcoat for diverse production needs.

FAQ
Answers to questions that commonly block an RFQ — so you can inquire with confidence.
What is the minimum neck diameter your machine can handle?
Standard down to 5mm. Smaller openings supported by custom long-nozzle solutions.
Can the machine spray both inside and outside of the bottle?
Yes. We offer interior-only machines and combined inside & outside spray lines.
What types of coating are compatible?
Solvent-based paint, water-based lacquer, and UV-cure coating. Gun and curing method are matched to your coating.
How to avoid overspray on the bottle exterior?
Long-nozzle internal guns with precise positioning, external masking fixtures, and negative-pressure recovery ensure zero exterior contamination.
Can an existing manual line be upgraded instead of replaced?
Often yes — send us your current layout and bottle drawing via the RFQ form for a retrofit assessment.
What is the production capacity?
500–6,000 bottles/h depending on configuration.
Do you provide installation and training?
Yes. Turnkey service includes on-site installation, commissioning, and operator training; 24/7 remote support.
What is the HS code for export?
Typically 8424.89 or 8424.30 (spraying machinery).
